Now let’s look at different mouth styles and their usage in manga drawing. These examples are solely based on what I believe is commonly used in manga. Once you find the style you prefer, you’ll need to stick to it throughout your manga. It is as important as maintaining the same eye style throughout.
This is one style of drawing a big smile, used in “girlish” manga mostly.
This is more of a generic smile. It’s simple and can be easily drawn.
This style gives more depth and definition to the mouth, as both the teeth and tongue are shown.
Another simple mouth style, used mainly for male characters.
This is an example of shouting, with the teeth shown.
One of my favorites, this can be used when the character is talking.
Another style used primarily for male characters. It emphasizes the lip’s shape, which makes the character more realistic.
